The internet is inherently insecure. Whenever you send data across it, there is a chance that that data could be sniffed, and someone could end up with your personal data. Hopefully once you've read this article, you'll have a better understanding of how to prevent this from happening.. When data travels through the internet, it needs to pass through multiple connections to get to its final destination. Most people don't realise that the data can be read by any machine it passes through on this journey. With the right tools, you can sniff this data yourself, and any data that passes through your network. This is because most networks actually send data intended for anyone on that network to all machines on your network, and your computer will ignore anything that's not meant for it. This is especially true for most wireless networks, even networks that are 'secured' with WEP/WPA. The link for this article located at Tux Radar is no longer available. .

Security researchers announced on Thursday the release of a network sniffing tool that conveniently categorizes the data leaked by laptops and other devices during routine operation. The tool, dubbed Ferret, analyzes information that computers and other network devices regularly send out as a matter of course--a problem that Robert Graham, CEO of startup Errata Security, called data seepage. . Ferret captures and analyzes the administrative parts of 25 different protocols--such as the Simple Mail Transfer Protocol (SMTP), the Common Unix Printer Service (CUPS), and Apple File Protocol (AFP)--to glean information about the target computer and its user. For example, a computer searching for a wireless connection will name all the access points to which it recently connected. As a computer's user roams the Web, the machine's Internet browser reveals a ream of information, including the computer's operating system, patch level of the browser and, of course, destinations.
